My car is basically stock, CF&D auto shifter, Pfadt springs, CF&d fresh air scoops and now the Solo high flow cats. There is a big improvement in sound, more of a growl. Everyone familiar with my car asks what I did right off because of the sound. Definately not loud in the cabin but sounds much better. More inportantly the performance. There is a definate increase in performance. My car always lights em up out of the hole but now it's been bouncing of the rev limiter before my second gear shift, no problem just got me by surprise a few times as I am pretty good at shifting consistantly. All in all I would recomend this upgrade to anyone.
